Question XL600R Headlight Trouble

Hello,

Long time reader, first time poster. I just picked up a 1985 XL600R. Before I got it running, the headlight as far I can remember worked fine with just the key in the 'on' position.

Today I got it running great, and now the headlight wont work at all. Running or not. Turn signals are working fine.

The bulb is good (swapped it out for another good one to check) , connections are decent as far I as I can tell everywhere.

Possible culprits?
- Rec/Reg? the other finned rec/reg(I dont remember which it is?)
- If so which one, and how do I test the current units to see if they good or not.
- Switch (how to test?)
- Stator? The headlights worked with just a battery as far I as I can remember
- (Battery is charged and healthy)

Any other ideas, I appreciate the help.

Could it potentially be a faulty ignition switch as well? The switch is a little finicky to get power through to turn on the neutural light, and the speedo light.

The headlight only works when the engine is running. Get a multimeter and start testing.

My high beam quit working the other week, turned out a soldered connection broke in the hi/lo switch.

If it is a US spec XL the headlight does not come on with the key. The headlight is powered from the stator with a/c current. The current gets voltage regulation, and none of the power goes to the battery, and battery voltage has no bearing on the headlight. The instrument lights and turn signals and brake light and horn are d/c (battery) powered.

If memory serves me well the yellow/white wire out of the stator is the headlight circuit. It travels to the dimmer switch and then headlight, no other switches involved. It just gets power when the engine is running only, and switches off so to speak with the engine.

Does the wire from the stator run through either of the reg/rec or the AC regulator?
